Two novel 2D coordination polymers, namely, {[Cu 2 (L) 2 ][Cu(H 2 O) 3 ]} n ( 1 ) and {Pb 3 (O 2 N‐btb) 2 } n ( 2 ) (O 2 N‐H 3 btb = 5‐nitro‐benzene‐1, 2, 3‐tricarboxylic acid, L = 5‐nitro‐2‐oxidoisophthalate), were synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectroscopy, X‐ray diffraction, and thermogravimetric analysis. Compound 1 is an infinite 2D layer exhibiting an extended 3D supramolecular network structure. O–H ··· O hydrogen bonding interactions play a key role in forming the final 3D supramolecular framework. It is noted that 5‐nitro‐benzene‐1, 2, 3‐tricarboxylic acid (O 2 N‐H 3 btb) was in situ transformed to 5‐nitro‐2‐oxidoisophthalate in 1 . Compound 2 is a 2D microporous lead‐containing metal‐organic framework made up of interconnected Pb‐carboxylate chains, involving three independent lead atoms with three different coordination arrangements. Furthermore, the solid‐state photoluminescence and lifetime characteristics of 2 reveal intense blue luminescence.
